Timing the release is important – if you release too early there aren't enough pest eggs for the wasps to parasitize - too late means that the pest eggs have hatched and you have a new problem - caterpillar pests.

Biology & Life Cycle:Trichogramma wasps lay their eggs inside the pest eggs, stopping development. The larvae feed on the egg and then emerge as adults. The larvae take 10 days to develop within the pest moth egg, which turns brown or black as the larvae pupate. The adult wasps live anywhere from 7 to 14 days, depending on temperature and moisture and the female Trichogramma will parasitize up to 300 pest moth eggs. Eggs on cards usually hatch within 2-5 days.

NOTE: Emergence holes are evident under significant magnification after Trichogramma have hatched.

Release Rate:

1 tab for 300 sq. ft. or 1 tab per tree in an orchard.

½ to 2 cards weekly per acre for 2 – 6 weeks.

Release immediately upon receipt. Release Trichogramma at first flight of moths and every 7-10 days thereafter until infestation subsides. It is best to release in the early morning or evening by hanging the cards out of direct sunlight, below plant tops or in trees where moths have been seen. Cards or tabs can be put on stakes or hung from the edge of a pot. Do not touch the eggs.

Using traps to monitor for adults and visual inspection of foliage to monitor for moth eggs will help determine the best time to release Trichogramma.

Storage: Release adult wasps immediately after emergence.

Conditions: Place in a warm location (80-90°F), out of direct sunlight. Hang individual cards where moths are seen.

After doing some research on a Trichogramma species to control a clothes moth infestation that was inside our walls, we turned to this product/species. We have placed half a card in 12 locations in our home where we thought were near the moths or where we didn't want any moths (like closets) for 5 consecutive weeks. The visible adult population has largely disappeared over this time. Prior to deploying these wasps, we would see and kill at least a dozen moths every day. I highly recommend this approach to tackling a difficult problem.
